BACKGROUND OF THE INVENTION

The present invention relates generally to the field of mobile devices, and more particularly to safeguarding private user data during audio communications.

In recent years, developments and the growth of Internet of Things (IoT) capable devices have created a wealth of opportunities to advance the capabilities to integrate systems. The internet of things (IoT) is the internetworking of physical devices (also referred to as “connected devices” and “smart devices”), vehicles, buildings, and other items, embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data. The IoT allows objects to be sensed and/or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy, and economic benefit in addition to reduced human intervention. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure.

Natural language understanding (NLU) is a subset of natural language processing (NLP) that uses computer software to understand input made in the form of sentences in text or speech format. NLU understanding of natural human languages enables computers to understand commands without the formalized syntax of computer languages and for computers to communicate back to humans in their own languages. At the core of natural language processing (NLP) lies text classification. A Natural Language Classifier (NLC) allows users to classify text into custom categories, at scale. An NLC applies deep learning techniques to make predictions about the best predefined classes for short sentences or phrases.

DETAILED DESCRIPTION

Embodiments of the present invention allow for secure voice communication over multiple computing devices and applications to safeguard sensitive information of a user. Embodiments of the present invention identify voice commands of a user with one or more computing devices. Embodiments of the present invention determines a context of a communication and an intent of a user utilizing a computing device. Additional embodiments of the present invention utilize the context of the communication, the intent of the user, and/or sensor data of the one or more computing devices to determine whether a set of conditions corresponding to mute/unmute functions are met.

Some embodiments of the present invention recognize that challenges exist with effective and secure voice communication over multiple computing devices and/or applications that safeguard sensitive information of a user. For example, a user issues voice command to a first computing device while having an open session on a second computing device, which can create confusion, trigger incorrect and non-intended command execution, and/or reveal personal data of the user to listening parties of the open session on the second computing device. Various embodiments of the present invention can perform mute/unmute functions for preventing exposure of sensitive information of a user to an unintended party based on analysis of context of the communication and intent of a user to switch the context of the communication for the purposes of task execution.

Embodiments of the present invention can operate to increase efficiency of a computer system by reducing the amount of processing resources the computing system utilizes by reducing the amount of tasks executed that correspond to unintended voice. Additionally, various embodiments of the present invention can improve hands-free computing technologies by utilizing cognitive solutions to increase the security of the computing system.

A variety of types of user interfaces exist. In one embodiment, user interface 132 is a graphical user interface. A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices, such as a computer keyboard and mouse, through graphical icons and visual indicators, such as secondary notation, as opposed to text-based interfaces, typed command labels, or text navigation. In computing, GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces which require commands to be typed on the keyboard. The actions in GUIs are often performed through direct manipulation of the graphical elements. In another embodiment, user interface 132 is a script or application programming interface (API). In another embodiment, user interface 132 is a voice-user interface (VUI) that uses speech recognition to understand spoken commands and answer questions, and typically text to speech (TTS) to play a reply.

In various embodiments of the present invention, server 140 may be a desktop computer, a computer server, or any other computer systems, known in the art. In general, server 140 is representative of any electronic device or combination of electronic devices capable of executing computer readable program instructions. Server 140 may include components as depicted and described in further detail with respect to FIG. 3, in accordance with embodiments of the present invention.

Server 140 can be a standalone computing device, a management server, a web server, a mobile computing device, or any other electronic device or computing system capable of receiving, sending, and processing data. In one embodiment, server 140 can represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server 140 can be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with client device 120 and other computing devices (not shown) within distributed data processing environment 100 via network 110. In another embodiment, server 140 represents a computing system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that act as a single pool of seamless resources when accessed within distributed data processing environment 100.

Server 140 includes storage device 142, database 144, and security program 200. Storage device 142 can be implemented with any type of storage device, for example, persistent storage 305, which is capable of storing data that may be accessed and utilized by client device 120, user device 130, and server 140, such as a database server, a hard disk drive, or a flash memory. In one embodiment storage device 142 can represent multiple storage devices within server 140. In various embodiments of the present invention, storage device 142 stores numerous types of data which may include database 144. Database 144 may represent one or more organized collections of data stored and accessed from server 140. For example, database 144 includes sensor data, voice commands, historical data, etc. In another example, historical data can include a set of conditions that correspond to a voice command or metadata (e.g., command types) of the voice command. Additionally, database 144 can include data corresponding to past interactions of a user with client device 120 via user interface 122. In one embodiment, data processing environment 100 can include additional servers (not shown) that host additional information that accessible via network 110.

Generally, security program 200 can analyze the context of a discussion of a user to determine whether to perform mute/unmute functions on multiple devices to assist a user in hands-free communication with multiple computing devices and/or applications. In one embodiment, security program 200 monitors user interface 132 of user device 130 and user interface 122 of client device 120 to identify one or more voice commands a user provides and corresponding tasks of the commands. In this example, security program 200 analyzes speech of a discussion the user transmits through client device 120 to determine whether one or more one or more sets of conditions exist to perform a mute or unmute function with respect to client device 120.

FIG. 2 is a flowchart depicting operational steps of security program 200, a program that identifies a context of a communication to determine an intent of a user based on historical data of the user communicating with other computing devices and/or applications using voice commands to automatically perform mute/unmute functions to secure sensitive information of the user, in accordance with embodiments of the present invention. In one embodiment, security program 200 initiates in response to a user connecting a computing device to security program 200 through network 110. For example, security program 200 initiates in response to a user registering (e.g., opting-in) a laptop (e.g., client device 120, user device 130) with security program 200 via a WLAN (e.g., network 110). In another embodiment, security program 200 is a background application of user device 130 that continuously monitors client device 120. For example, security program 200 is a client-side application (e.g., application 134) that initiates upon booting of a laptop (e.g., user device 130) of a user and monitors data of a mobile device (e.g., client device 120).

In step 202, security program 200 monitors communications of a user utilizing a computing device. In one embodiment, security program 200 captures audio data of a user utilizing client device 120. For example, security program 200 utilizes a microphone of a mobile device (e.g., client device 120) and/or laptop (e.g., user device 130) proximate to a user to capture audio data (e.g., speech, voice commands, discussions, etc.) of the user. In this example, security program 200 can utilize the audio data to train a synthesizer algorithm of a speech recognition system (e.g., user interface 122, user interface 132, speech to text (STT), text to speech (TTS), etc.) to identify and learn voice commands the user uses to interact with computing devices (e.g., client device 120, user device 130, etc.) over time (i.e., collects historical data). Additionally, security program 200 utilizes the audio data to determine a context of a discussion (e.g., communications) of the user.

In an example embodiment, a user communicates a voice command to user device 130 to “open a file” (e.g., folder, location, etc.) of user device 130, which requires authentication (e.g., a password, sensitive information, etc.), and “save policy records file”. In the example embodiment, security program 200 utilizes a microphone of client device 120 to capture the voice command of the user and stores the voice command in database 144.

In step 204, security program 200 identifies a voice command of the user. In one embodiment, security program 200 identifies a voice command in audio data of the user to a computing device. For example, security program 200 uses a microphone of a mobile device (e.g., client device 120) to detect a voice command of a user. In this example, security program 200 utilizes learned commands (e.g., collected historical data) to determine a command type (e.g., shell, social, web) of the detected command. A shell command can relate to a directory-based system, which can be utilized to identify a location (e.g., path) in a directory of every file, folder, and application of a computing device. A social command can relate to a request-response system (e.g., interactive system), which can be utilized for “what” type of questions. A web command can relate to a web-based command system, which can be utilized to access a uniform resource locator (URL) using a default web browser (e.g., application 124, application 134). Additionally, security program 200 determines a specific task corresponding to the voice command of the user. In alternative example, security program 200 may utilize a microphone of one or more computing devices (e.g., user device 130) to detect voice commands of the user.

In the example embodiment, security program 200 utilizes a microphone (e.g., sensor 136) of user device 130 to detect a user is transmitting the voice command (e.g., open policy records file) to user device 130 and determines that the voice command corresponds to a “shell” command type. Security program 200 can then monitors user device 130 to identify the task (e.g., retrieve folder that includes policy records file) corresponding to the command and update database 144.

Generally, security program 200 can utilize natural language understanding (NLU) techniques to analyze semantic features of text input (e.g., voice commands, responses to voice commands, speech, etc.) including categories, concepts, emotion, entities, keywords, metadata, relations, semantic roles, and sentiment to determine a context or intent of a user based on audio data corresponding to communications. Additionally, security program 200 utilizes a natural language classifier (NLC), which is an ensemble of classification models, along with unsupervised and supervised learning techniques, to achieve its accuracy levels. After assembling training data (as discussed in step 202), security program 200 utilizes the NLC to evaluate textual representations of audio data against multiple support vector machines (SVMs) and a convolutional neural network (CNN) to categorize service queries (e.g., voice commands, shell commands, etc.) and corresponding tasks.

In step 206, security program 200 determines an intent of the user. In one embodiment, security program 200 utilizes audio data of a user to determine an intent of the user. For example, security program 200 monitors conversations of a user to determine an objective (e.g., intent, task, etc.) of the user. In this example, security program 200 utilizes NLU techniques to identify a topic of speech of a conversation (e.g., audio data) of a user and another party as well as a corresponding objective. Additionally, security program 200 utilizes an NLC to identify a service query (e.g., voice command, keywords, etc.) associated (e.g., relations) with the corresponding objective. Furthermore, security program 200 can utilize NLU techniques to identify metadata (e.g., command types, object locations, etc.) to determine whether the service query associated with the corresponding objective can be performed on a mobile device (e.g., client device 120, application 124, etc.) of the user.

In the example embodiment, security program 200 utilizes a microphone of client device 120 to monitor audio data (e.g., conversation) transmitted between the user and another party (e.g., insurance agent). In this example, security program 200 determines using NLU and speech of the audio data that the user and the insurance agent are discussing a policy file (e.g., topic) that the user needs to retrieve (e.g., objective, intent, task, etc.) in order to provide the insurance agent requested information. Additionally, security program 200 utilizes an NLC to identify a voice command associated with the task (e.g., retrieve) and topic (e.g., policy file) based on historical data of database 144 and determines that the voice command is a “shell” command type, which includes a location of the policy file. Furthermore, security program 200 can utilize NLU techniques to identify metadata (e.g., the policy file locations) to determine whether the voice command associated with the corresponding task can be performed on client device 120 of the user or user device 130. In one scenario, security program 200 determines that the location of the policy file points to a location of user device 130, then security program 200 can determine that the user intends to switch to another device or application to execute the corresponding task (i.e., determines the intent of the user).

In step 208, security program 200 determines a context of the communications of the user. In various embodiments of the present invention security program 200 identifies a context of an audio communication between a user and another party. Additionally, the context is a set of conditions correlated to audio communications of the user that indicate security vulnerabilities (e.g., exposure) of sensitive information (e.g., personal data) of the user, which may include voice commands, tasks corresponding to the voice commands, availability of active audio applications and/or computing devices of the user.

In one embodiment, security program 200 determines a context of audio data a user transmits to another party via client device 120. For example, security program 200 identifies one or more conditions that indicate that unintentional transmission of sensitive information of a user via a mobile device (e.g., client device 120, application 124, etc.) is probable. In this example, security program 200 determines whether an objective (e.g., intent, task, etc.) corresponding service query (e.g., voice command) is associated with exposure of sensitive information of the user. In one scenario, if security program 200 determines that a voice command (e.g., shell type command) correlates to retrieving a file (e.g., task) that requires user authentication (i.e., a user must provide a password), then security program 200 determines that a privacy condition exists. In another scenario, if security program 200 determines that a voice command (e.g., social type command) that requires a digital assistant (e.g., application 124) to generate a response (e.g., task) that includes personal identifiable information (e.g., personal data) of the user, then security program 200 determines that a privacy condition exists.

Additionally, in this example security program 200 determines whether a computing device (e.g., client device 120) can unintentionally transmit the sensitive information of the to an unintended party. In one scenario, if security program 200 determines that a mobile device (e.g., client device 120) of the user is transmitting audio data to another party, then security program 200 determines that an exposure condition exists. In another scenario, if security program 200 determines that a mobile device (e.g., client device 120) of the user is broadcasting audio data via a social media application (e.g., application 124), then security program 200 determines that an exposure condition exists.

Furthermore, in this example security program 200 identifies one or more computing devices (e.g., user device 130) within a defined proximity to the user that can perform the objective of the user. In one scenario, if security program 200 determines that one or more computing devices (e.g., user device 130) that are capable of executing the task corresponding to the voice command are within a threshold distance (e.g., audible distance of client device 120), then security program 200 determines that a proximity condition exists. In another scenario, if security program 200 determines that an active digital assistant (e.g., application 124) of a mobile device (e.g., client device 120) of the user is capable of executing the task corresponding to the voice command, then security program 200 determines that a proximity condition exists.

In decision step 210, security program 200 determines whether mute conditions are present. In one embodiment, security program 200 utilizes client device 120 and user device 130 to determine whether a set of conditions of a context exist that indicate executing a mute function of client device 120. For example, security program 200 determines whether one or more conditions of a context (as discussed in step 208) indicate that unintentional transmission of sensitive information of a user via a mobile device (e.g., client device 120, application 124, etc.) are present. In this example, security program 200 determines whether privacy, exposure, and proximity conditions exist and whether to execute a mute task of a computing device (e.g., client device 120).

In another embodiment, if security program 200 determines that a set of conditions of a context exist that does not indicate executing a mute function of client device 120 (decision step 210, “NO” branch), then security program 200 continues to monitor audio data of a user utilizing client device 120. For example, if security program 200 determines that a voice command (e.g., shell type command) correlates to retrieving a file (e.g., task) that does not require user authentication or include personally identifying information, then security program 200 continues to utilize a microphone of a mobile device (e.g., client device 120) of a user to monitor audio data (e.g., speech, voice commands, discussions, etc.) of the user.

In another embodiment, if security program 200 determines that a set of conditions of a context exist that indicates executing a mute function of client device 120 (decision step 210, “YES” branch), then security program 200 mutes client device 120. For example, security program 200 determines that a voice command (e.g., shell type command) correlates to retrieving a file (e.g., task) that requires user authentication (e.g., a password) (i.e., identifies a privacy condition) and a mobile device (e.g., client device 120) of the user is transmitting audio data to another party (i.e., identifies an exposure condition). Also, security program 200 determines that a laptop (e.g., user device 130), which is capable of executing the task corresponding to the voice command, is within a threshold distance of the mobile device (i.e., identifies a proximity condition). As a result, security program 200 prohibits the ability of a microphone of the mobile device to capture audio data of the user.

In the example embodiment, security program 200 identifies the voice command associated with the task (e.g., retrieve) and topic (e.g., policy file), which is a “shell” command that includes a location of the policy file that is password protected (i.e., identifies a privacy condition). Additionally, security program 200 determines that a user is utilizing client device 120 to speak with the insurance agent (i.e., identifies an exposure condition). Furthermore, security program 200 utilizes near field communications of client device 120 to detect user device 130 (i.e., identifies an exposure condition). As a result, security program 200 mutes the phone application the user is utilizing to speak with the insurance agent.

In another embodiment, security program 200 utilizes data of sensor(s) client device 120 or client device 130 to monitor actions of a user to confirm a set of conditions exist indicate executing a mute function of client device 120. For example, security program 200 utilizes a camera (e.g., sensor 126, sensor 136) to collect gaze tracking and body motion data of a user to confirm that the user is currently engaged (e.g., attention, interactions, etc.) with a secondary device (e.g., user device 130) or application (e.g., application 124) within proximity to the user that is capable of executing a specific task corresponding to a voice command (i.e., confirms the set of conditions indicate to mute client device 120).

In step 212, security program 200 mutes the computing device. In one embodiment, security program 200 mutes client device 120. For example, security program 200 disables a microphone (e.g., sensor 126) of a mobile device (e.g., client device 120) of the user, which prohibits the collection of audio data of an operating environment of the user. In another example, security program 200 utilizes the set of conditions as discussed in step 210 to determine whether to delegate a mute task to the application specific agent (e.g., application 124) or to a computing device (e.g., client device 120) mute function.

In decision step 214, security program 200 determines whether unmute conditions are present. In one embodiment, security program 200 utilizes a status of a task corresponding to a service query user device 130 performs to determine whether to execute an unmute function of client device 120. For example, security program 200 determines a status of a task corresponding to a voice command of a user that a digital assistant (e.g., user device 130) performs and whether to execute an unmute task of a computing device (e.g., client device 120). In another embodiment, security program 200 utilizes client device 120 and user device 130 to determine whether a set of conditions exist that indicate executing an unmute function of client device 120. For example, security program 200 determines whether one or more conditions indicate that unintentional transmission of sensitive information of a user via a mobile device (e.g., client device 120, application 124, etc.) are no longer present. In this example, security program 200 determines whether privacy, exposure, and proximity conditions exist and whether to execute an unmute task of a computing device (e.g., client device 120).

In another embodiment, if security program 200 determines that a set of conditions do not exist that indicate executing an unmute function of client device 120 (decision step 214, “NO” branch), then security program 200 continues to monitor conditions of an operating environment of client device 120. For example, if security program 200 determines that privacy, exposure, and proximity conditions are present in an operating environment of a mobile device (e.g., client device 120), then security program 200 does not execute an unmute task of the mobile device and continues to monitor conditions of the operating environment of the mobile device.

In another embodiment, if security program 200 determines that a set of conditions exist that indicate executing an unmute function of client device 120 (decision step 214, “YES” branch), then security program 200 unmutes client device 120 (step 216). For example, if security program 200 determines that a privacy condition is not present in an operating environment of a mobile device (e.g., client device 120) (i.e., the information corresponding to the user is not sensitive), then security program 200 allows a microphone (e.g., sensor 126) of the mobile device to capture audio data of the user.

In the example embodiment, security program 200 identifies the voice command associated with the task (e.g., retrieve) and topic (e.g., policy file), which is a “shell” command that includes a location of the policy file that is password protected (i.e., privacy condition is present). Additionally, security program 200 determines that user device 130 completed the task (i.e., an exposure condition is no longer possible). As a result, security program 200 unmutes the phone application (e.g., sensor 126) the user is utilizing to speak with the insurance agent.

In step 216, security program 200 unmutes the computing device. In one embodiment, security program 200 unmutes client device 120. For example, security program 200 enables a microphone (e.g., sensor 126) of a mobile device (e.g., client device 120) of the user, which allows the collection of audio data of an operating environment of the user. In another example, security program 200 utilizes the set of conditions as discussed in step 210 to determine whether to delegate an unmute task to the application specific agent (e.g., application 124) or to a computing device (e.g., client device 120) mute function. In another embodiment, security program 200 unmutes client device 120 in response to detecting a command of a user. More specifically, in response to security program 200 detecting a voice command of a user to unmute mobile device (e.g., client device 120), security program 200 transmitting instructions to execute a task to reenable a microphone of the mobile device.
